I read about this in Weyger's book, and wondered if anyone has ever done this? seems like it would be a good way to do some specialized cuts on hardened stuff, kinda like a chop saw.

Hey Sam
I have done this on my old shop smith to cut down a sizable sheet of 3/8 mild, and it works fine, but don't expect it to cut as fast as wood 🙂
It took a while, but was pleased with doing square cuts, and not having to resort to using a sawzall or 4.5" grinder.

Sam: Look for one of the old small belt drive saws,not the newer direct drive ones.They can be found pretty cheap on Craigslist.The belt drive won't bog down on you. Watch the RPM's. I learned about that one from Weygers too.He was a very interesting man who practiced what he preached. His house in the Bay Area was built from 100% recycled materials.

Gene Chapman has a "tool room cutoff wheel" mounted on an arbor. Sort of what you are talking about. The disks are much thinner than the usual abrasive cut off disk. Maybe Gene will chime in with the facts of the matter when he wakes up from his nap.

Good Morning,

Abrasive blades work good, BUTT, DON'T CUT STEEL AND ALUMINIUM WITH THE SAME BLADE!!!

Thermite is aluminum and steel filings, burns at over 6000 degrees. Thermite will burn a hole in concrete and your building will be gone!!!Cry

Railway rails are welded together with Thermite.

The size I use is7" X .035" with hole size 1 1/4". These will cut off hardened steel, just not too thick.

noticed the 7" ones have various hole sizes.

Hey Sam:

I used a cut-off wheel on a table saw years ago before I had a torch or an angle grinder. I would Never go back to it. Firstly, it's dangerous... If you are like me you mark your metal with a line and then by eye, you cut to the line... Well, If the wheel comes apart, what is directly in line with it? Your face and your eye. I found it also to be very slow compared to a zip disc on an angle grinder or even a torch. I also found that unless you have an enclosed motor on your table saw, the metal grindings will kill your motor within a year. Now, I have put a cut-off wheel on a skilsaw and cut sheet steel with that. Worked pretty darn well. Good luck, take care... I am impressed with some of your work... Just wish you lived closer so we could play in the shop.

lately at work we have been using a skill saw with a metal cutting blade. cut slow and steady and the end results are actually pretty good. you can also clamp a guide to the piece for a nice straight cut. If your piece is too narrow to clamp a guide to, tack it to the edge of a table. Flush your tacks with a grinder and cut away! oh, and wear safety glasses, a face shield, long sleeves, and gloves! those little chips are HOT! ask me how I know!

good luck!
